Master Lock S3910 Wheel Valve Lock Off Device

The Master Lock S3910 Wheel Valve Lock Off Device is designed to prevent the accidental opening of pressurised gas valves during maintenance and servicing work. It surrounds the gas valve handle to support safer isolation procedures and can be used on valves with or without guarding.

Its patented design fits virtually all valves up to 3in (76mm) diameter and works with Master Lock or American Lock safety padlocks and lockout hasps. It also allows multiple workers to apply their own personal safety padlocks, making it well suited to group lockout applications.

Please note: the Master Lock 487 is not supplied with a padlock.
